limited available frequency spectrum for next generation technology and demand for high …

In the last decade there is a vast development in the wireless communication and new
wireless devices so the demand of the radio spectrum is increasing, There is a need of …

Dynamic spectrum access and cognitive radio are emerging technologies to utilize the
scarce frequency spectrum in an efficient and opportunistic manner. Cognitive radio, built on …

Cognitive radio allows opportunistic spectrum access by finding and using temporally and
spatially unused radio channels to enhance the utilization of scarce radio spectrum. Various …

In this paper, spectrum sensing methods analysis and comparison are presented. The
spectrum sensing techniques implementation challenges and issues are discussed in detail …

Data Transmission plays an important role in the digital world. This transfer occurs via point-
to-point data streams or channels. These channels may previously have been in the form of …

Spectrum sensing is the process of identifying available spectrum channels for use by a
cognitive radio. In many cases, a portion of the spectrum is licensed to a primary …

In this paper, two well-known cognitive radio spectrum sensing (CR-SS) methods, energy
detection (ED) and matched filter (MF), are numerically realized in time domain (TD) as well …

Scarcity of available spectrum and the inefficient usage of the same motivated the
researchers to look for solutions in Dynamic Spectrum Access (DSA). Cognitive Radio (CR) …
